The New Zealand British Rail Mark 2 carriages were built by British Rail Engineering Limited for British Rail in the early 1970s. From the mid-1990s, 150 were exported to New Zealand. After being rebuilt, refurbished and re-gauged, they entered service with a variety of operators on New Zealand's railway network. The carriages generally replaced older NZR 56-foot carriages, some of which had been in use for almost 70 years.
